:ldb

Arguments: &optional mode

This command controls the installing (enabling) and uninstalling (disabling) of breakpoints, and the establishment of ldb mode. The functional equivalent is the with-breakpoints-installed macro.

When given no arguments, this command prints the current mode. When given t as an argument, ldb mode is entered, and when given nil, an attempt is made to quit ldb-mode.

Note that in order to do stepping (see :step), you must be at a breakpoint.

See The Lisp DeBug (ldb) stepper in debugging.htm for information on ldb stepping. See top-level.htm for more information on top-level commands.
